Readiness score

78/100

Readiness measures how much verified integration surface exists for builders and agents. It does not mean the protocol is easy to use — integration difficulty is tracked separately.

Capabilities

Agent identity registry beta

Best for: portable agent identities, agent registration files, A2A, MCP, ENS, DID, and service endpoint discovery

  • ERC-8004 is still a draft ERC; production users should track spec and contract updates.

Reputation and validation registries beta

Best for: public feedback signals, trust scoring inputs, agent validation records

  • Reputation aggregation, Sybil resistance, and validator incentives need separate design.

Composes with

x402 payments_and_commerce supports

x402 supplies the paid HTTP request/payment rail that ERC-8004-registered agents can use for monetized services.

  • agent service discovery plus per-request payments

the-graph indexing_and_data supports

The Graph can index agent registry, feedback, and validation events for discovery surfaces.

goldsky indexing_and_data supports

Goldsky can stream agent registration, reputation, validation, and marketplace events.

Known issues

ERC-8004 is a draft standard and does not include payment rails medium confirmed Workaround: Use ERC-8004 for agent identity, reputation, and validation; use x402 or another payment layer for settlement; monitor the EIP and contract repository for changes.
